Description
Collision strengths for transitions among the energetically lowest 53 fine-structure levels belonging to the (1s^2^ 2s^2^ 2p^6^) 3l^2^, 3l3l', 3s4l and 3p4s configurations of Fe XV are computed, over an electron energy range below 160Ryd, using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2003, Comput. Phys. Commun., in prep.). Effective collision strengths, obtained after integrating the collision strengths over a Maxwellian distribution of electron energies, have also been calculated. These results of effective collision strengths are tabulated for all 1378 inelastic transitions over a wide temperature range of 10^5^ to 10^7^K. Comparisons are also made with other R-matrix calculations and the accuracy of the results is assessed.
